Application filed July so, 1190?. Serial No. 386,178.

To all whom it may concern:

Be it known that I, ANTON C. Soma- "MANN, a citizen of the UnitedStates, and

-=t'ion is'to do away with the necessity for cutting through any threadsin order to form the waste channel, and yet so construct the parts thatthey are not increased in size-thereby saving metal and labor,securingbeauty of design. and convenience in handling, reducing cost,and still not impairing the successful operation of the whole.

The invention is exemplified in the structure hereinafter described, andit is defined in the appended claims.

In the drawings formlng part of this specificatlon, Figure 1 1s acentral sectional view with the main valve closed and the wastevalveopen. Fig. 2 is a similar'section with the parts in their oppositeposi tion; Fig. 3 is a side elevation of the stem and plunger removed.Fig. 4: is a section of parts showing a modification. Fig. 5 is a detailview of a modification.

In the drawings the numeral 1 designates the body of the cock which ishere shown and as a part of the cap 4;, and is herein shown assurrounding the stem with an annular space 15 between them which formspart of the waste passage and communicates through the chamber 4 withthe waste outlet 16. Above the waste valve seat and referably at theupper end of the cap 4: is ocated packing 7 which is compressed by apacking nut 6.

A valve stem 8 extends through the nut 6 and packing 7, loosely through"the seat 14 so as to form the space 15, and into the extension 3, whereit is secured to or integral with an enlarged plug or plunger 17 whichhas exterior guides, here shown as threads 10 engaging interior ides,here also threads 10 within the le wer part of the extension. At theupper part of the latter these threads are omitted so as to form anenlarged smooth bore 3 for a purpose de scribed. below. v

The mam valve 22 1s here shown as a disk held by a screw 24 within ashell 20 at the lower end of the plug, and of reduced exterior diameter;and the waste valve 18 is in this instance a ring held within a shell l7at the upper end of the plug, and also of reduced diameter so thatbetween its outer surface and the inner surface 3 of the enlarged smoothbore of the extension 3 there is a space 19 which when the plug islowered as in Fig. 1 allows free access of the Waste to the space 15 andoutlet 16. Above the shell of the main valve the plug may be exteriorlyreduced as at 21 to form a neck, but this feature is unnecessary if the"outer surface of this shell at a point where the passage 23 enters isalways out of contact with the threads 1O when wasting. The object ofreducing the diameter of the plug has been hereinbefore set forth.

The waste passage 23 is shown as a hole bored obliquely through the plugfrom the neck 21 to where it opens into the space 19. By preference thishole is straight as shown, so that it may be easily drilled, but if itis desired to clear the tip of the screw 24 or any other reason shouldexist, the hole might be bored from each end with an angle between itsextremities as indicated at 23? in Fig. 4, or in any other way; andhence I do not limit myself to the shape and size of this hole, nor evento but one such hole,

so long as its extremities communicate with the reduced ends of theplug, whether the narrow neck 21 is used or not. It will be obvious thatto drill the hole through the plu in this manner is simpler than to outa groove in the threads 'on the plug or within the extension, or both,and it leaves less chance for wear or for the obstruction of parts.

In the operation of the complete device, the main valve stands closed asshown in Fig. l and the waste liquid under waste pressure only isflowing upward through the hole 23, space 19, passage 15, through thewaste valve chamber-4 and out the waste exit 16. When the handle 9 isturned in proper direction to open the main valve, the plug is'drawnupward until the waste valve closes against its seat as shown in Fig. 2,and while this may not close the lower end of the hole 23 it does shutoil the initial pressure from the waste.

The construction herein illustrated permits the omission-of the reducedneck 21, because as shown in Fig. 1 the lower end of the waste passage23 communicates with the outlet side of the through passage in the headof the body 1.

It is quite within the possibilities of this invention that the plungermay be moved by other means than the stem and handle shown in Fig. 1.For instance,- the stem might be longitudinally movable, with its lowerend swiveled in the plunger. In fact, it is not absolutely essentialthat the plunger shall rotate, so long as it has movement in and isguided within the body extension so as to open one valve and close theother at either extreme of its movement. For instance, the threads whichconstitute the guides might be grooves in the extension to be engaged byribs on the plunger, the latter being formed as in Fig. 5, and then anysuitable means could be employed for moving the latter-in its guides.Furthermore, I do not limit myself to placing the valveson the'plungerand the seats in the body, as this arrangement might be reversed ateither end although I prefer the construction shown. In brief, the gistof the present invention. lies in forming the waste passage through theplunger by coring out a hole on a line which occupies a general obliquedirection between its extremities, and either reducing the diameter ofthe plunger op posite the ends of said passage or increasing the size ofthe body at those points, or both, so as to permitthe waste to flowthrough such passage as has been herein described.
